What are the 3 major ocean zones?
The ocean is generally divided into three zones which are named based on the amount of sunlight they receive: the euphotic, dysphotic, and aphotic zones.
- Euphotic Zone (Sunlight Zone or Epipelagic Zone)
- Dysphotic Zone (Twilight Zone or Mesopelagic Zone)
- Aphotic Zone (Bathypelagic, Abyssopelagic, and Hadopelagic Zones)
What are the major life zones?
The epipelagic zone, mesopelagic zone, bathypelagic zone, abyssopelagic zone, and the hadalpelagic zone are the major marine life zones. Each zone is characterized by depth, with the hadalpelagic zone being the deepest. Epipelagic -Sunlight reaches this zone.

five zones
The ocean is divided into five zones: the epipelagic zone, or upper open ocean (surface to 650 feet deep); the mesopelagic zone, or middle open ocean (650-3,300 feet deep); the bathypelagic zone, or lower open ocean (3,300-13,000 feet deep); the abyssopelagic zone, or abyss (13,000-20,000 feet deep); and the
How many life zones are there in the world?

What are the 5 main zones in the ocean?
The ocean water column is made up of five zones: the sunlight zone (epipelagic), the twilight zone (mesopelagic), the midnight zone (bathypelagic), the abyssal zone (abyssopelagic) and the hadal zone (trenches).
What does life zone mean?
Definition of life zone
: a region characterized by specific plants and animals.
Where is the oceanic zone?
The Oceanic zone extends from the edge of the continental shelf over the continental slope to the ocean floor beyond. It begins where the water is over 200 meter (656 feet) deep. This zone contains deep trenches, volcanoes, and ocean basins.
Where is the pelagic zone?
“Pelagic zone is the region of the ocean outside the coastal areas and is also known as the open ocean.”

What are the 3 types of aquatic biomes?
Aquatic biomes are divided into marine and freshwater biomes based on salt content. Marine biomes are further divided into coral reefs, seas and ocean biomes, and estuaries biomes. Freshwater biomes are lakes and ponds, rivers and streams, and wetland biomes.
What is the name of the first zone of the ocean?
Epipelagic Zone – The surface layer of the ocean is known as the epipelagic zone and extends from the surface to 200 meters (656 feet). It is also known as the sunlight zone because this is where most of the visible light exists. With the light come heat.
What is a marine zone?
Marine zones include beaches or strands, intertidal/infratidal, littoral/sub-littoral, bathyal, abyssal, ultra-abyssal, epipelagic, mesopelagic, bathypelagic, and abyssopelagic zones…

What ocean zone is the Titanic in?
The Titanic lies at 3,800 meters or about 12,500 feet. This area of the ocean is known as the Bathyal zone. The average temperature is 39° F. The pressure at this depth is 5,850 pounds per square inch.
What zone do sharks live in?
Deep sea sharks live below the photic zone of the ocean, primarily in an area known as the twilight zone between 200 and 1,000 meters deep, where light is too weak for photosynthesis. This extreme environment is limited in both sunlight and food.
How are life zones classified?
In 1947, Leslie Holdridge published a life zone classification using indicators of: mean annual biotemperature (logarithmic) annual precipitation (logarithmic) ratio of annual potential evapotranspiration to mean total annual precipitation.
Why are biomes called the major life zones?
biome, also called major life zone, the largest geographic biotic unit, a major community of plants and animals with similar life forms and environmental conditions. It includes various communities and is named for the dominant type of vegetation, such as grassland or coniferous forest.
How are life zones determined?
Life-zone definition
Any of a series of biogeographic zones into which a continent, region, etc. is divided by both latitude and altitude on the basis of the characteristic animal and plant life in a zone.
